Slow boot after OC?

[CapsLuke]

Hi everyone, i currently overclocked my i5-3570K from 3.4ghz (3.8 boost) to 4.1 ghz and after 1 hour of p95 test i think it's pretty stable. The fact is that now my pc takes longer to boot, but once booted performance is perfect! What's the issue?
Settings i touched: vcore from auto (which on cpuz reached 1.36V O.O) to 1.28V
Llc to high
Power capability from 100 to 120%
Disablead spread spectrum
Multiplier to 41
My rig
Intel i5-3570K @4.1ghz
16 gb DDR3 1333mhz
RX 480 8GB sapphire nitro+
Asus P9Z77 - V
Psu Cooler Master RS600 ACAB M2

thanks for your help

Try going back to stock settings and seeing if it still does it.

lower the v core to dafault then restart overclock but without going over 1.3 in voltage and test .

 

[CapsLuke]

Haven't tried yet but what if the problem still occurs even resetting default?

 

[The_Staplergun]

Depends on the results. Just give it a try and see what happens.

 

[scout_03]

try cmos reset to restore bios to default .

 

[CapsLuke]

Restored default and still slower boot, any suggestion?

How much longer are we talking and where does the hangup happen? In the bios splash screen, or on the whirlydig under the windows logo. Does it continuously spin if it is windows or does it freeze.

after windows logo, i got the same screen black with the windows spinning dots (win 10) but they seem at lower resolution and less fluid, sometimes there's written please wait in a blue screen (not bsod, there are widonw's spinning dots too)

 

[The_Staplergun]

Sounds like an issue with windows. Could have corrupted during instability in overclock testing. I'd try starting in safe mode and then restarting to see if it rectifies.

If not, try a reset through control panel (gear in start menu, backup and reset, reset this computer, keep my files)

 

[CapsLuke]

I'll try that tomorrow and post the update, thanks for your disponibility mates

Update: right now i am at the university so i cannot reset my pc, but yesterday after about 1 hour of bf1 (which brings my cpu from 75 to 100% usage) and 1 hour and 30 minutes of p95 test, my pc rebooted automatically... why? My oc seems kinda stable...

 

[The_Staplergun]

That means it's actually unstable. You need to try stepping up another 0.005 on the voltage.

 

[CapsLuke]

Thats strange... many people can get 4.3/4.4 ghz on 1.150 v and i cant be stable at 4.1ghz @1.272V... why? And also this damn strange boot...

 

[The_Staplergun]

Silicon lottery. Your chip isn't as efficient. Some people win some people don't.

 

[CapsLuke]

the fact is that i'm on aftermarket cooler (artic freezer 13) and on stress test with this voltage i get highest peak on core 3 (from 1 to 4) at 88 degrees and average MAXIMUM 82.2 C. Would bringing it to 4.0 ghz affect stability without undervolting/increasing voltage?

 

[The_Staplergun]

Lowering the frequency without lowering the voltage just results in effectively providing too much voltage. It's not bad but not necessary.

If you're at 4.3 or 4.4 you can step down to 4.2 and try that with a little less.

i am at 4.1ghz right now, and i experienced a spontaneous reboot after 2h 30 min of p95 test/bf1 @ultra. what i meant was: would it be better increasing voltage, or leaving the voltage like that and downclocking to 4.0ghz? (consider the temps showed before).

 

[The_Staplergun]

You're not running too high of a voltage. Youre borderline stable if it runs that long just fine.
Just up it by 0.005 and try again.

 

[CapsLuke]

I will later i update u

 

[CapsLuke]

Upadate: here's what i did:
I set vcore to 1.115v and multiplier to 35. Slowly i am increasing multiplier and voltage when i get errors. Right now an overnight p95 test resulted positive with 37x multiplier at 1.144V and the boot error is slowling going away: now the black screen with low resolution dots appears just for a second sometimes less as long as i increase voltage and vcore (so you were right, i had to increase voltage). Later this evening i'll continue increasing core and voltage when it needs to, i'll keep you updated

 

[CapsLuke]

Why can i keep fully stable 3.7ghz while 3.8 isn'stable even at 1.176V?

 

[The_Staplergun]

More than likely you've hit the physical limitation of that chip.

 

[CapsLuke]

But 3.8ghz is just the exact boost speed 🙁

 

[The_Staplergun]

Ah, well it takes more voltage to run above stock settings. You'll have to pump in more voltage.
